The composition of the office chair.#office chairs


1. Casters Ordinary casters, PU wheels (soft materials, suitable for wooden floors, and machine rooms).

2. The thickness of the chair leg iron frame directly affects the service life of the chair. Surface treatment: spray paint, baking varnish (surface gloss, not easy to remove paint), electroplating (wood frame can not be electroplated), the electroplating quality is good, and it is not easy to rust.

3. The air rod is also called the extension rod, which is used to adjust the height and rotation of the chair.

4. The part where the chassis supports the seat, and the bottom is connected with the air rod.

5. The seat of the chair is composed of wood, sponge and fabric. The quality of wood boards is usually not felt by consumers. Sponge: recycled cotton, new cotton. 99% of manufacturers use the two together, the thicker and harder, the higher the cost, the thickness is appropriate, and the hardness is appropriate. Press the seat with your hands, fabric: Ma Rong, mesh, leather. The plastic frame is pressed into the net cloth. This type of chair is more in line with breathability.

6. Handrails.

7. Seat back seat connection (corner code) The seat and the back of the chair are separated, and they are connected by steel pipe or steel plate. The steel plate is usually 6mm or 8mm thick. However, steel plates with a width less than 6 cm must be 8 mm thick.

8. The chair back steel frame and plastic frame are made of mesh fabric, which is breathable.

9. The lumbar pillow reflects the comfort of the chair.

The office chair is composed of seven parts: a seat, an air rod, a back, a tray, a caster, a five-star claw, and an armrest.

Because office chairs are used in different locations and ways, they are generally fixed or sliding. There are two ways to join the chair wheel or the fixed seat and the chair leg: threaded type and spring ring embedded fixed type. The sliding chair wheels use different materials to match the sliding speed of the chair due to the different hardness of the floor used to increase safety. Hard floors use soft wheels (PU), and soft floors use hard wheels (NYLON).
The basic function of the chair is to support the user's body while working or resting. The office chair is required to be used in both working and resting states. Therefore, the office chair has tilting and lifting functions to achieve this requirement. The lifting of the office chair is realized by an air bar, and the tilting function is realized by the tilting mechanism of the tray.

In different working environments, the adjustment of the back angle of the office chair can help the user improve the posture of the back and reduce the pressure on the back. The office chair can adjust the forward tilt angle to match the user's physical activity to provide a correct sitting posture, which can reduce the pressure on the user's legs.

The seat can also be locked forward. Assuming that the user’s work requires long-term use of the computer, locking the seat forward can help the lower back have a greater angle of movement, and can reduce the pressure on the spine. The sliding of the chair wheel can help the user to move quickly in an appropriate range, which is convenient for the dragging of the chair and the adjustment of the seat.
